A novel concept for an atmospheric solid oxide fuel cell (SOFC) hybrid system applying a sub‐atmospheric gas turbine is proposed. Based on a developed process model suitable operating conditions are studied. The resulting performance is compared to different state‐of‐the‐art SOFC system concepts. The comparison shows that pressurized SOFC/GT systems offer the highest electric efficiency. The novel concept as well as a two‐stage SOFC system offer lower efficiencies, but still well above 60%. However, avoiding the complex system requirements of pressurized SOFC/GT systems, these concepts are promising for highly efficient electricity generation.

新型大气SOFC / GT混合过程的建模以及与最新SOFC系统概念的比较

提出了一种应用低于大气压燃气轮机的大气压固体氧化物燃料电池（SOFC）混合系统的新概念。基于已开发的过程模型，研究了合适的操作条件。将所产生的性能与不同的最新SOFC系统概念进行比较。比较表明，加压的SOFC / GT系统可提供最高的电效率。新颖的概念以及两级SOFC系统的效率较低，但仍远高于60％。但是，避免了加压SOFC / GT系统的复杂系统要求，这些概念对于高效发电很有希望。
